More Information
Summary:The utility model discloses a lithium cell equalizing charge circuit for electric automobile, select part, balanced charge -discharge part including interchange - direct current conversion portion, detection control section, battery cell. Interchange - direct current conversion portion converts 220V's alternating current into 330V and 12V's DC voltage through the transformer, and the controller calculates the battery that need charge alone on the basis of detecting battery cell voltage, electric current, temperature, and control battery cell selects the part to open the 12V DC voltage by the partial equalizing charge who accomplishes the battery of balanced charge -discharge. This circuit is opened the battery package at charging system in the quick charge later stage, and the difference of reducible each battery cell capacity has and switches nimble reliable, balanced efficient advantage.
